IMPROVEMENT IN MEAT-CHOPPERS.

Specification forming part of Letters Patent No. 120,359, dated October 24, 1871.

To all whom it may concern:

Be it known that I, NATHANIEL TRUE WORTH- LEY, of Brunswick, in the county of Cumberland and State of Maine, have invented a new and valuable Improvement in Meat-Choppers; and I hereby declare that the following is a full, clear, and exact description of the const-ruction and operation of the same, reference being had to the annexed drawing making a part of this speciiication, and to the letters andigures of reference marked thereon.

Figure l of the drawing is arepresentation of a side elevation of my invention.

This invention has relation to an improved mechanical motor for actuating meat-choppers, churn-dashers, Snc., and the novelty consists in the construction and arrangement of devices, hereinafter described, by means of which avertical reciprocating and intermittent rotary motion is given to an upright shaft.

Referring to the accompanying drawing, A represents a standard supported on a horizontal sill, B, and provided with a projecting beam, C. D represents a tub having a central projection, d, on its bottom, fitting a recess cut in the sill B to hold it steady. E indicates a rotary shaft horizontally arranged in the standard A, and holding on its outer and inner ends, respectively, a crank, e, and a ily-Wheel, el. The latter is formed with a circular grooved flange, e2, on its inner face, and is provided with a crank-arm, e3, to operate it by. F designates a rod, bent to the form of an inverted U, one of whose legs is longer than the other. j' represents the long and f the short leg. To the end of the latter is secured a head-block, g, from which projects a shaft, g1, one end of which is attached to a collar, g2, secured to the leg f. The legs j' f are arranged to slide up and down through vertical holes cut in the bracket C. The shaft g1 is connected to a crank, e, by means of a pitman, G, through the medium of which reciprocating vertical motion is given to the rod F and its connections.

The leg j' slides through a bracket, IL, projecting from the standard A, and serving as a guide and strengthener to said leg. H indicates a vertical shaft, to which it is designed to give reciprocating vertical and intermittent rotary motion. It is armed with a pair of curved cutters or choppers, t', secured to its lower end. On its upper end is a loose sleeve, 7c, which fits an aperture formed through the bracket g, and is held therein by means of a thumb-screw, k1. Below this sleeve a toothed wheel, k2, is secured to the shaft H, and is given an intermittent motion by means of a spring, I, which is secured at one end to the pitman G, and is form ed with a beveled edge, to engage with the teeth of the wheel k2. The lateral vibration ot' the pitman renders the actuation of this wheel, by the means described, intermittent. The upper end of the spring I is bent to rest on'lthe shaft g1. M represents a treadle hinged to-the sill B, and coupled to the collar g2 by means of a rod, N. This treadle is to be used when footpower is desired instead of hand-power, or together with it.

I claim as my inventionl. The combination of the rotary shaft H, wheel k2, spring I, pitman G, and crankshaft E, as and for the purpose set forth.

2. The rod F, head-block g, screw k1,pitman G, and shaft E, in combination with the shaft H, provided with the toothed wheel k2, and loose collar k, as and for the purpose set forth.

3. The treadle M, hinged to the sill B,- and connected to the collar g2 by the rod N, in combination with the shaft E, pitman G, and rod F, as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses l NATHANIEL TRUE WORTHLEY.
